aiup-vaadin is the AI Unified Process layer plugin for the UI and E2E layers of a Vaadin application. It builds and tests the views of a use case — server-side Java views with Vaadin Flow, or React views with Hilla — on top of the service layer, and automates use cases and test case journeys in the browser with Playwright and Drama Finder.

It is one plugin of a layered setup: a project combines aiup-core with one plugin per layer. The skills are driven by aiup-core and need aiup-core 3.0.0 or later:

/stack records in docs/architecture/stack.md which skill builds and tests each layer
/use-case-implement UC-XXX runs the implementation skills bottom-up and hands each layer the Handover of the one below
/use-case-test UC-XXX runs the test skills from the integration layer up — for a Flow UI the Browserless tests, which run against the real service and database, so no service or repository tests are written below them; behind a Hilla UI the service tests
/use-case-coverage UC-XXX audits the use case against the markers this plugin writes into the Markers table

Every skill can also be run directly.

Skills

Layer	Skill	Result
UI	`/vaadin-flow-ui`	`@Route` views, lazy grids, Binder forms, dialogs, notifications
UI	`/hilla-ui`	`@BrowserCallable` endpoint delegating to the service, and the React view
UI	`/vaadin-flow-ui-test`	Browserless view tests `UC<id><Name>Test` with `@UseCase`
UI	`/hilla-ui-test`	Vitest view tests `UC-XXX-<slug>.test.tsx` with the endpoint client mocked; one Java endpoint contract test (access, messages)
E2E	`/vaadin-e2e-test`	Playwright + Drama Finder tests for a `UC-` or a `TC-` journey

A project uses either the Flow pair or the Hilla pair for its UI layer; /vaadin-e2e-test works with both.

Combinations

Project	Plugins next to `aiup-core`
Vaadin Flow, jOOQ	`aiup-flyway`, `aiup-jooq`, `aiup-spring-boot`, `aiup-vaadin`
Hilla, jOOQ	`aiup-flyway`, `aiup-jooq`, `aiup-spring-boot`, `aiup-vaadin`

Replace aiup-jooq with aiup-jpa for a JPA persistence layer. The views call the service layer of aiup-spring-boot directly and need no API layer — Hilla's endpoint is part of /hilla-ui. A REST API (/spring-rest) may still exist for other clients; it then tests only its own contract, and the integration layer stays the Browserless tests of a Flow UI or the service tests behind a Hilla UI.

This plugin replaces the UI and test half of the combined aiup-vaadin-jooq plugin for layered projects. Karibu Testing is not carried over; Browserless Testing supersedes it.

Installation

Tessl

tessl install ai-unified-process/aiup-core
tessl install ai-unified-process/aiup-spring-boot
tessl install ai-unified-process/aiup-vaadin

Claude Code

/plugin marketplace add ai-unified-process/marketplace
/plugin install aiup-core
/plugin install aiup-vaadin

Claude Code installs aiup-core and aiup-spring-boot with this plugin; Tessl does not, so name them as above. Install the plugins of the other layers (aiup-flyway, aiup-jooq or aiup-jpa) the same way. Do not combine layer plugins with the combined aiup-vaadin-jooq plugin in one project. See the marketplace installation guides for other agents and manual adoption.

MCP servers

The plugin configures the Vaadin documentation server and the Playwright server; both are optional. See rules/mcp-servers.md.
